Aurélien M. A. Leguy,Yinghong Hu,Mariano Campoy-Quiles,M. Isabel Alonso,Oliver J. Weber,Pooya Azarhoosh,Mark van Schilfgaarde,Mark T. Weller,Thomas Bein,Jenny Nelson,Pablo Docampo,Piers R. F. Barnes +11 more
TL;DR: In this paper, it was shown that hydrated crystal phases are formed when methylammonium lead iodide perovskite (MAPI) is exposed to water vapor at room temperature and these phase changes are fully reversed when the material is subsequently dried.
Journal ArticleDOI
Experimental and theoretical optical properties of methylammonium lead halide perovskites
Aurélien M. A. Leguy,Pooya Azarhoosh,M. Isabel Alonso,Mariano Campoy-Quiles,Oliver J. Weber,Jizhong Yao,Daniel Bryant,Daniel Bryant,Mark T. Weller,Jenny Nelson,Jenny Nelson,Aron Walsh,Mark van Schilfgaarde,Piers R. F. Barnes +13 more
TL;DR: The calculations indicate that the orientation of [CH3NH3](+) cations has a significant influence on the position of the bandgap suggesting that collective orientation of the organic moieties could result in significant local variations of the optical properties.
Journal ArticleDOI
Relativistic origin of slow electron-hole recombination in hybrid halide perovskite solar cells
TL;DR: In this paper, the authors show that slow recombination originates from a spin-split indirect gap, which shifts band-edges to inequivalent wavevectors, making the fundamental gap indirect.

Journal ArticleDOI
Quasi-particle electronic band structure and alignment of the V-VI-VII semiconductors SbSI, SbSBr, and SbSeI for solar cells

TL;DR: The ternary V-VI-VII chalcohalides consist of one cation and two anions and have a multi-valley electronic structure with several electron and hole basins close to the band extrema.
